METHODICAL GUIDELINES FOR THE STRUGGLE AGAINST CHICKEN EIMERIOSIS IN FARMS AND PRIVATE SUBSIDIARY HOLDINGS

Abstract

The comprehensive data on the prevalence of chicken eimeriosis in farms and private holdings, types of causative agents, epizootological features, diagnostic methods, and struggle measures with the use of modern preparations are presented. The extensive analysis of economic significance of eimeriosis for poultry farms is provided. Virulent Eimeria species are presented. By 60 days of age, 78,3 % of free range chickens were infected by Eimeria, 63,8 % of which were heavily infected. In 72,7 % of cases chicken eimeriosis occurred in the form of mixed infection with Ascarididae, Heterakis and/or Capillaria. Data on the infection focus and diagnostic methods are provided. The list of anti-eimeriosis remedies from different chemical groups with a schedule of their alternation for prevention of development of resistant strains of Eimeria is created. Measures for prevention of chicken eimeriosis, and remedies for disinvasion of premises are proposed.
